| Abstract: | In order to meet the need of various application, four kinds of coaxis three-mirror-anastigmat ,tem were designed. The design method of initial configuration of on-axis three-mirror-anastigmat system was outlined based on principle of on-axis three-mirror-anastigmat system, and four kinds of coaxis three-mirror- anastigmat system were optimized with spectral region of 0.45-0.9μm, effective focal length of 10m, f number of 10. These systems could achieve fine imaging quality that approached the diffraction limit over field of view. The characteristics of parameter of optical system, layout of components, field format and butting FPA were analyzed in this paper, It will be the application to space-based observations that determines the optical system configuration of coaxis three-mirror-anastigmat with long focal length. |
